Graeme has taken a car that was constantly having issues (lots of time spent on the side of the road) to a car that purrs (well growls – did I mention that Graeme is a V8 tuning whiz?)

We were struggling to find a garage that would give us decent service for our ’76 Statesman Caprice. My wife suggested we take it to Graham at GT Automotive. On meeting Graeme and discussing the issues we were having I was impressed with Graeme's’ immediate grasp of what needed doing.

Got Graeme to build me a 355 holden engine. He stripped my 308 down and bored it to 335. He put in Scat rods, Forged pistons & Molly rings, Comp cam springs & retainers. Ported 308 big valve heads, Scorpion roller rockers, Fully blueprinted& balanced.400+hp. There are a lot of good mechanics out there and Graeme North is one, and a very likeable guy.

Thanks GT automotive for the work you put into getting my 70 Corvette ready for compliance and running right. The work done was first class, I would have no hesitation in bringing my other performance vehicles to have work done, thanks once again Graeme.
